    摘要： A method/system for measuring cylinder pressures of an internal combustion engine includes a crank angle sensor utilized to generate pressure readings at known angular intervals. Additional time-based pressure measurements are taken in selected angular windows between a pair of the angle-based pressure readings. Because the angle-based pressure measurements and the time-based pressure measurements occur at known times, the pressure as a function of the crank angle for the time-based pressure measurements can be determined. The cylinder pressure measurements can be utilized to calculate combustion parameters used for closed-loop engine control of fuel supply or other engine inputs.

    摘要翻译： 一种用于测量内燃机的气缸压力的方法/系统，包括用于产生在已知的角度间隔的压力读数的曲柄角传感器。 附加的基于时间的压力测量是在选定的角度窗口的一对基于角度的压力读数之间。 因为基于角度的压力测量值和基于时间的压力测量值发生在已知时间，压力作为基于时间的压力测量值的曲柄角度的函数可以是确定性的开采。 气缸压力测量值可以用于计算用于燃料供给或其它发动机输入的闭环发动机控制的燃烧参数。

    摘要： Method of estimating the mass enclosed in the combustion chamber of a cylinder of a motor vehicle internal combustion engine, equipped with a means of measuring the pressure in the cylinder, with a means of measuring the angle of the crankshaft with respect to a reference position and of measuring the temperature of the combustion chamber cooling liquid. The method comprising steps during which the rotational speed of the engine is determined from the measurement of the crankshaft angle and the engine load is determined. The method also comprises the following steps: when the valves of the cylinder are completely closed and before fuel is first injected, the volume of the cylinder is determined as a function of the angle of the crankshaft, calibration parameters connected with the heat losses at the walls are determined from a map dependent on engine rotational speed, the temperature modelled in the cylinder is determined using a non-linear dimensionless model of the pressure and the temperature in the combustion chamber as a function of the measured pressure in the cylinder, of the specific gas constant for the gases in the cylinder, of the specific heat capacity at constant volume of the gases in the cylinder, of the volume of the combustion chamber, and of calibration parameters connected with the heat losses at the walls, and the mass enclosed in the cylinder is determined.

    摘要： A system for monitoring of the fuel self-ignition angle, especially in the cylinder of a diesel engine applying Langmuir probe is described. A two-channel metal adapter (2) with pressure indicator (6) and Langmuir probe (3) is placed in an engine cylinder(1). In the indicator channel a pressure sensor (7) is placed, which generates a signal which is sent to the electronic pressure recorder (10). Langmuir probe (3) is connected with a power source (4) and signal amplification set-up (5), which is connected with the fuel self-ignition angle recorder (13). The monitoring system includes the Top Dead Centre (TDC) signal generator (8), which signal is transmitted to the TDC signal divider (9), which after galvanic separation is transmitted to the electronic pressure recorder (10), the vibration recorder (11), the crankshaft revolution timer (12) and the self-ignition angle recorder (13). The vibrational sensor (16), sends its signals to the vibration recorder (11) but the signal from the self-ignition angle recorder (13) is sent to numerical indicator of self-ignition angle (15) and the signal determining the value of angular velocity to its numerical indicator (14); finally, export of data from the self-ignition angle recorder (13) is performed through data transmission set-up (17) to external monitoring systems.
    An alternative system for monitoring of the fuel self-ignition angle (presented in Fig. 2) contains a pulsed, rotating transducer (18) generating 3600 pulses per crankshaft revolution (0,1 ° CA) - replacing less precise determination of TDC by an inductive sensor. The rotating transducer (18) generates TDC signal, which is transmitted to the signal divider (9).
    Advantage of the invented monitoring system is placement of the Langmuir probe in engine cylinder, which enable direct determination of moment of fuel ignition in working engine.

    摘要： A system and method for calibrating an absolute angular position sensor and/or for providing pre-calibrated absolute angular position sensors comprises comparing, at a pre-elected number of angular positions, the angular position derived from the output of the sensor to the angular position reported by a reference sensor. The difference between the two outputs is used as an error correcting factor for the respective position. In addition to calibrating the sensor to reduce sensor errors, the calibration can also be used to determine the sensor output corresponding to an index position of interest.
